HEATING APPARATUS.

To all whom it may concern;

Be it known that I, AARON l'l. WoLrr, a citizen of the United States, residing at the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Heating Apparatus, of which the following is a specification, reference being had therein to the accompanying drawings, which form a part thereof.

My invention relates to heating apparatus, and more particularly to a type thereof containing a plurality of radiator elements, each of Which has therein a gas or similar burner. The general type of apparatus to which my invention relates is old and Well known in the art, the purpose of my invention being to prevent the discharge of noxions gases from such an apparatus into a room either as the result of a delayed or imperfect ignition of the gas at the various burners, or as the result of imperfect combustion due to an inadequate or improperly controlled circulation of air Within the several elements, or to the impingement of a flame, from any burner upon the metal portion of the different elements, by reason of the formation of said elements, or variation in the flame due to drafts or uncontrolled air currents about the burners.

In an apparatus made in accordance with my invention, the several heat radiating elements are so constructed and so united, as to be completely closed at the bottom there of, while being in communication with each other in a manner to secure substantial uniformity in the distribution of the heat throughout all of the elements while permitting the use of a supply conduit for gas, common to all of said elements. The man ner of connecting the several elements is such that a large chamber, passing through the assembled. structure is formed, the walls of said chamber being spaced, at all points,

sufficiently away from the burners to minimize any likelihood of the flame or flames impinging upon any metalportion of the several elements. The walls forming said chamber are so formed as to space the several elements apart in a manner to facilitate the proper circulation of air through each element while so bafliing, or directing, the air flowing through one element as to prevent the passage thereof to an, adjoining element in a manner to deflect the flame jet Specification of Letters Patent.

and cause it to impinge upon said walls. This bafl'ling effect, however, is of secondary importance since each of the elements is provided with an air inlet and air outlet so disposed in relation to each burner, as to minimize likelihood of any side deflection of the jet in said element.

The provision of the chamber above described, also permits the utilization of an igniting device common to all of the burners in the assembled apparatus which lighting device is normally so positioned when not in use as to be out of the range of the flame jets from the several burners while being readily brought to the operative position to permit the simultaneous ignition of the gas emerging from all burners, at a single point of this lighting device. This device is'sp constructed in the assembled apparatu as to prevent the admission of air throughthe lighting port while the apparatus is in operation, and prevent the channel member used for transmitting flame to the gas emerging from the separate burners, fromremaining accidentally in a position where the flames will impinge thereon. By using a structure including a lighting device for the purposes above referred to, I not only secure convenience in the lighting of the burners in the several elements, but avoid an accumulation of'gas within, and its escape from, the apparatus, prior to the ignition of all of the burners, such as would necessarily follow from admitting gas to the apparatus without confining and controlling the initial flow of gas from the several burn ers in a manner to permit this gas to be utilized for lighting purposes.

I also provide means by which the pipe carrying the several burners, may be quickly and accurately positioned within the chamber formed adjacent the bottom of, and common to, the several elements or sections,

which means will also prevent the displacement of the burners in installing the apparatus.

The invention consists in the novel features of construction and. combination of parts hereinafter set forth and described and more particularly point-ed out in the claims hereto appended.

Referring to the drawings,

Figure 1 is a side view, partly in elevaembodying my invention;

tion and partly in section, of an apparatus Fig. 2 is a section on the line 2-2 of Fig. 1;

Fig. 3 is a section on the line 3-3 of Fig. 1; and

5 Fig. 4 is a perspective View of a portion of the channel plate for simultaneously igniting all of the burners.

. In ethe accompanying drawings, .1 have shown a four element, sectional radiator consisting of two end sections aa and two intermediate sections a-a Eachof these sectionsprefenably comprises two side plates formed from sheet steel and permanently unitedby Welding or in any other desired or approvedmanner. In formeach ofthe elements or sections'is suchas to afford a large radiation surface, one outside dimension of each element being very much greater thanthe other, thus presenting a high, narrow chamber which willinsure theiheating gases being brought into sufficiently close proximity to the metal to cause the heat of said gases to be readily andconstantly transferred tothe metal of the element.

Theconstruction of each end section or element is substantially alike and differs from theintermeidiate sections merelyin the addition of supporting'legs Zrandin form'- .ingjthe nipple 0 so as to afford a proper bearing for the ends ofthe tie-bolt 0f holdingth'e upper portion of each element in the assembledapparatus in the proper position relative to every other element.

Any desired number of intermediate sections may-be employed each of which will .be similar to every other, but will differ in the respects above noted from the end ele- .ments orsections. The description of one of these sections will, therefore,'be entered .40 into, similar reference letters indicating similar parts upon the different-sections.

Slightly above the bottom of each section,

I form a. large opening in each side plate,

themetal of said plate adjacent said opening'being turned or formed outwardly at substantially right anglesto the surroundsing portions of the plate, the edge of said metal being turned inwardly of the opening,

to form a-flange to facilitatethe uniting of adjacent elements or sections adjacent .the

bottom thereof. The outwardly turned portion, whichmay betermed a distance ring, is indicated at d and :the flange thereon at d. The bolts passingthrough the flanges are indicated at 0?. i The opening-within the rings d is substantially elliptical with the major' axis extending vertically. Adjoining elements .or sections .are .in communication .through the opening within the rings to (Z thus forming :in the entire lower portion of the assembled apparatus a continuous chamber in which the various burners are situated. The portion of each of the elements at to a aboveithe rings, constitutes a 6,5 dome adapted to receive ,the heated gases.

secured thereto. permanently secured to these fittings and the the tie-bolt c to pass through all of said :nipplessecurmg the various elements or sections together ad acent the top thereof. l lxtending from endto end of the apparatus is a pipe f carrying aplurality of burners f, a

burner bemgpositioned directly below the dome formed by the portion of each element or section above'the ring (Z. Preferably, I employ burners of the fant ail type, although, any desired form-of burners may be used, it beingdesirablc, however, to so seteach burner as to have the flare of the flame extend in the direction of the greater horizontal dimension of the "as dome or of the element with which said burner is associated.

To permit accuracy in the positioning of the'burners, and avoid likelihood of their being displaced when installing the apparatus, I mount the opposite ends of the pipe in a fitting adapted to seat upon the outer rings (Z of each end section, and to be tirml The ends of the pipe are coupling for a flexible gas tube or other connection with the pipe f, is secured to this fittlng instead of directly to the end of the pipe This fitting comprises a plate 1 adapted to conform to the inside of the outer plate of the respective end sections or elements aa the lower edge of this fitting conforming to the curvature of-the ring (1. Carried by the plate 9 areofisets lugs g having bolt openings therein. These lugs bear upon the inside of the outer plate of said sections respectively and are secured thereto by means of rivets or bolts as desired. The plate 9 is also provided with a nipple 9 extending beyond the ring (I. The pipe 7 is suitably fitted to the inner end of the nipple g by means of ordinary screw threads while the outside of the nipple n is used as a means for attaching a suitable coupling 9 or an ordinary cap to said fitting. By this means it is impossible for the pipe and its various burners to be turned when nstalling an apparatus, since the end fittings carried by said casirg tal-ze up any stresses which, were it not for the provision of this means preventing the turning of the pipe, would be transmitted to said pipe.

'The opening within the outer rings d of the end elements or sections a a are closed by caps h-JL having openings therein through which the nippleg projects.

To .insure the proper circulation of air withinithe chamber near the bottom of the assembled apparatus, which chan'llzer is common to all of the elements or sections, as well as in the individual domes above said chamher, I provide an air inlet below the pipe 7 and an air outlet adjacent the top of each dome. To minimize any tendency toward a side deflection of the flame from the burner, I employ a plurality of air inlet openings z upon opposite sides of each burner, or in each of the side plates of each element or section, so as to secure the admission of air upon opposite sides of each burner. If desired, the air outlet may consist of a plurality of openings j adjacent the top of each dome in each side plate, although, this is not essential so long as the proper relative capacity of the air inlet openings z' and of the outlet openings j, is maintained. By locating the various openings '5 below the rings d, I secure a baffling effect by the side walls adjacent said rings and by the flanges cl, so that while air is permitted to pass freely through the rings d, the direction of flow will ordinarily be at an angle which will not tend to deflect the flame from the burner of the adjacent element or section.

To insure a substantially simultaneous ignition of the gas merging from the several burners 7,1 provide a movable channel plate normally positioned away from the several burners while being adapted to be brought over said burners to confine the gas emerging therefrom and convey it to an ig nition port at some point in the apparatus,

so that the initial flow of gas will be confined within the channel in the plate, and be utilized. for conveying a flame to each of the burners. The plate 70 and the actuating means therefor are so constructed as to automatically maintain this plate away from the jet openings in the burners. Said actuating means preferably includes a closure for the ignition port.

In the accompanying drawings, T have illustrated a simple and effective manner of inounting'and controlling the plate 70 which consists of end brackets 7a7c having open.- ings therein by means of which said brackets are pivotally mounted upon the pipe 7. These brackets are connected to the plate 70 by a slot and screw connection, as shown, to insure the proper adjustment of the plate. The plate 70 is provided with weighted sections k adapted to normally overbalance the plate and cause it to drop in the position indicated in the dotted lines in Fig. 2. Said plate Z3 is provided with a channeled extension is, the channel of which leads from the channel in said plate and terminates adjacent a suitable opening in one wall of the apparatus. As a matter of convenience, I prefer to cut away the portion of two adjoining rings d and close the opening thus formed by a fitting m having an opening or port m adjacent the end of the extension 70". Hinged to said fitting m is a closure n having a lug a thereon, said closure being operatively connected with the plate 70 by means of the link or connecting rod 0 pivotally onnected with said lug and with the extension 70*.- The extension M is arranged substantially midway between the ends of the plate it, thus insurin uniformity in the rate of transmission of the flame to the burners of the apparatus. This, however, is merely a matter of convenience and is not essential to the invention.

To prevent the plate 70 being brought to and remaining upon a vertical center above the burners f, I provide the brackets 'c70 with a tongue 72 which is adapted to engage a stop pin 9" carried by the plate 9.

The operation of the herein described apparatus is substantially as follows When an apparatus is being constructed, any desired number of elements or sections may be incorporated therein, it being merely essential that the pipe 7 shall be of a length to permit a burner f to be positioned di rectly below the dome of each element or section. The manner of assembling an apparatus made in accordance with my invention is apparent from the foregoing descrip tion, it being merely necessary to point out that when so assembled, the entire lower portion adjacent, and for a considerable distance above each of the burners, is entirely free of obstruction of any kind, either directly above the burners or above and at either side thereof. This condition is presented in the outer plates of the end sections also since the caps hh are spaced well away from the burners. It is to be noted that each of the domes leading from the chamber thus formed, is free of obstruction excepting the tie-bolt 0 adjacent the top of said dome which is sufheiently removed from the burner to avoid the formation of a carbon, or soot, deposit thereon.

This construction facilitates a more perfect combustion of the gas discharged from the several burners f and avoids fouling of the radiatino surfaces within the apparatus as well as tie discharge of noxious gases through the air outlets ,4. By arranging the air inlet openings below each of the rings (j upon op posite sides of each element or section, I secure a substantially direct vertical flow of air and insure the delivery of a sulficient volume thereof about each burner to properly promote combustion while at the same time avoiding the flickering of the flame in a manner which would tend to cause a flame even of illuminating gas, to smoke.

When it is desired tolight the burners in theapparatus, it is merely necessary to turn on the gas and raise-the closure n. The raising of th closure oscillates the plate A? and brings the channel therein directly above each of the burners. As the gas from the burners impinges upon the plate within this channel, it flows through this channel to the extension and from the end of the channel in this extension toward the port m in the fitting m. By presenting a lighted match at this port, the gas-will be ignited at this point and the flame will be conveyed directly over each of the burners in a manner to ignite the gas coming therefrom. The position of the plate 70 above the several burners f not only furnishes an ignition charge in the manner above referred to, but prevents the escape of gas within the chamber toward the bottom of the apparatus and within the several domes, thus avoiding likelihood of the escape of gas. When it is necessary to cause the gas to flow into the apparatus until a sufficiently rich mixture is secured to permit ignition at the port, with out the use of the plate 70, the air in the room will be sufliciently vitiated and the gas within the apparatus will be burned in a manner t0 foul the apparatus. Substantially instantaneously with the ignition of the gas at theport m, the closure a may be released, the weight of this closure and of the overbalancing weights 76* upon the plate 7:, automatically removing the said plate from above the burners and presenting a clear field for the flame jets.

' By having each of the elements or sections completely closed at the bottom, the floor underneath the apparatus is protected from any dirt which may have accumulated in the apparatus, as well as from-the heat of the several burners. The tongue 70 and the stop pin 9 limit the movement of the plate is and prevent its being positioned so that it will not automatically close when the closure 12 is released.

-It is essentialin an apparatus made in accordance. with my invention,that a burner be provided below each heat dome in order to secure high efliciency in the apparatus. By providing forproper and adequate circulation of air within the chamber adjacent the bottom of the apparatus, and through the several domes, I secure a sufiiciently perfect combustion of the gas. High efficiency in the apparatus is also secured by reason of the utilization of substantially all of the heat units developed therefrom the radiation of this heat from the several elements or sections and utilization of the heated gases emitted from the outlet opening. The degree of perfection in the combustion of the gases avoids the likelihood of vitiation of the air in a room by noxious gases flowing from the apparatus.

. It is not my intention to limit the invention to the precise details of construction shown in the accompanying drawings, it being apparent that such may be varied without departing from the spirit and scope of the invention.
